I would like to send a cell into a function, and have each matrix plotted from the cell. How can I input legend based on changing inputs?

Example:

function [  ] = AVG_Plot_Function(X,Degrees,Data )
for k = 1:size(Data)
  AVG{k} = mean(Data{k},1)
  a{k} = polyfit(X,AVG{k},3)
  b{k} = polyval(a{k},X)
   plot(X,AVG{k},X,b{k})
   legend(Degrees(k)...)  ..> this only puts the last entry, need all the labels.
   hold on
 end
end

在 MATLAB Online 中打开

axes('NextPlot', 'add');  % as "hold on"
LineHC = cell(1, numel(Data));   % [EDITED]
for k = 1:numel(Data)   % Not SIZE!
   AVG{k} = mean(Data{k},1)
   a{k} = polyfit(X,AVG{k},3)
   b{k} = polyval(a{k},X)
   LineHC{k} = plot(X,AVG{k},X,b{k});   % [EDITED]
end
LineH = cat(1, LineHC{:});   % [EDITED]
legend(LineH, Degrees);
